Wesbound traffic on I-90 in Willoughby near Kirtland Road backs up because of a semi truck crash Wednesday morning. The westbound lanes between Route 44 and 306 were later closed due to multiple crashes.

Snow created slick driving conditions Wednesday on the portion of Interstate 90 that runs through Lake County, leading to more than 20 vehicle crashes in a 10-hour period.

The multitude of crashes also prompted the Ohio Highway Patrol to close sections of I-90 in both directions for part of the morning and afternoon.
